Does anyone actually use the "Pick Corners" feature, and does it actually work for them?

Here's the documentation on it: https://community.microvellum.com/portal/en/kb/articles/adding-subassembly-inserts-and-using-pick-corners#Adding_SubassemblyInserts_and_Using_Pick_Corners

It's never worked for me. I pick the corners for the opening and it does it's magic... the problem being the "Base PointY" & "Base PointZ" always come out wayyy off (like 900ft away...)

If I were to manually update the values, I could probably make it work but that's not how it's supposed to work.

Ain't nobody got time for that!

What's the deal with this? Is it just me?
